The daring racecar driver, "Burn 'Em Up" Barnes, (Jack Mulhall) meets failing business owner Marjorie Temple (Lola Lane) and becomes her partner. What Marjorie doesn't know is that the land she inherited from her father is worth millions in oil and that the devious racetrack owner, John Drummond (Jason Robards, Sr.), and his cronies are out to steal it. With help from Barnes and his young friend, Bobbie (Frankie Darro), Marjorie faces catastrophe, episode after episode! The racing stunts, crack-ups and fights are top notch in one of Mascot Pictures' most action-filled cliffhangers.
